There is such a special exhibition area at the scene of the skills competition. The achievements of technological innovation and innovation on the exhibition platform have played a role in the major national projects and contributed to the scientific research and production.

Experts in the folk! All these inventions and creations were born in the hands of ordinary front-line technicians in scientific research and production of China Electronic Technology Group Corporation. With the concept of excellence and innovation, the vigorous people of electronic technology have realized their own value promotion while the enterprise is developing rapidly, and have walked out a way of innovation with military characteristics. Here are three employee inventions.

3D printing technology: little yellow duck log in China

When the huge "duck fleet" landed in England and America, no one would think that 20 years later, CETC has such a group of "RuiChuang space" young people, giving a new image to the little yellow duck. This not only benefits from the inspiration of Hoffman, the Dutch Master of art, but also benefits from the popularization and development of 3D printing technology. From then on, these shower toys from China come back to our hometown with a new look, let's recall the beautiful memories of childhood again.

According to the traditional method, it takes about 7 or 8 steps to make a common little yellow duck: to build a sketch, to make a module, to carve a model of little yellow duck, to make a mold, to inject the melted plastic into the mold with pressure, and then to cool the mold······

Now just draw a three-dimensional little yellow duck in the computer, press the "OK" key, and a real little yellow duck will be "printed", which is 3D printing technology. Generally speaking, it's like a cake shop mounting a cake. The cream nozzle in the master's hand piles the delicate cream layer by layer on the cake to design a three-dimensional cake shape. The biggest difference between 3D printer and traditional ink-jet printer is that the "ink" it uses is a real raw material. With the continuous progress of this technology, the "RuiChuang space" team has been able to produce 3D models that are very close to the appearance, feeling and function of the prototype. 3D technology has obvious advantages such as high-speed, integrated molding and so on. It has played an important role in scientific research, manufacturing industry, architectural design and other fields.

One night before the Spring Festival in 2013, a dozen young people sat quietly beside the 3D printer. The cold weather didn't cool the hot feelings of these young people. They had been fighting for four consecutive nights. When the 230 ° C nozzle dragged the melted filaments around, a dozen pairs of bloodshot eyes were staring at the gradually formed little yellow duck. Peng Wei, the team leader, wrote down the number of "9" in his notebook. Yes, the previous 8 times have failed... When the nozzle with a thread of melting filament slowly rises from the top of the yellow duck, the scene is boiling. It's a success! Four days and four nights, more than a dozen young people finally hit the "little yellow duck" to let everyone see the hope!

Three days later, RuiChuang space, the first Innovation Studio of CETC, was officially established. 3D printing technology has become the first pilot project with advanced concept introduced by RuiChuang space in China.

Peng, as a young team leader, resisted a lot of pressure when he introduced 3D printing technology. At that time, few people knew what 3D technology was. He was keen to capture the opportunity that the third industrial revolution would drive the rapid development of 3D technology. He and his team became the first people to eat crabs. As military engineers, they devote themselves to studying how to serve the advantages of 3D printing technology resources in scientific research and production. They use open-source hardware and software technology to complete the assembly of 3D printer parts and realize the successful operation of the printer. Through Pro / E, Autodesk and other digital modeling tools, they independently carry out forward and reverse model design, and successfully achieve the 3D model printing production of radar products Instead of the old way of making radar model outsourcing, the cost is directly saved by nearly one million yuan.

RuiChuang space continues to explore the way of military civilian integration of 3D printing technology, and changes the structure design from the traditional serial design mode to the synchronous collaborative mode. It has become an important auxiliary design means of full 3D structure typewriter in the industrial modeling design, wind tunnel test, structure design, assembly, interference inspection and other aspects of military products, which can greatly shorten the development cycle of radar.
